Feroni Dini Method Consolidation Of Wall Paintings

The Ferroni–Dini method allows cleaning and consolidation of mural paintings affected by sulfates, avoiding the detachment of the fresco from the wall. The method consists of two steps: the first is the application to the painted layer of a saturated solution of ammonium carbonate, (NH 4 ) 2 CO 3 ; the second is the treatment with a barium.

Feroni dini method consolidation of wall paintings. Applications of nanotechnology to wall paintings consolidation and paper deacidification have recently provided clear evidences of the huge potentiality of this emerging science for cultural heritage conservation [4-7]. Historically, the Ferroni-Dini method, also called the “barium” method, was the first method that provided A novel class of p-xylene-in-water microemulsions mainly based on nonionic surfactants and their application as low impact cleaning tool in cultural heritage conservation is presented. Alkyl polyglycosides (APG) and Triton X-100 surfactants allow obtaining very effective low impact oil-in-water (o/w) microemulsions as alternatives to pure organic solvents for the removal of polymers. The method has been applied with the same excellent results to the wall paintings' pre-consolidation, as well as stone consolidation, and conservation of mortars, stuccos and mosaics (Baglioni et. The present paper reviews the sulphatisation process and the peculiarities of both the Ferroni-Dini method and Ca(OH)2 nanotechnology for pre-consolidation, cleaning and consolidation of wall.

Calcium hydroxide (Ca(OH) 2) is one of the most interesting materials used to consolidate stone sculptures, monuments, mortars or wall paintings.In this study, we reported on the synthesis and characterization of surface modified Ca(OH) 2 nanoparticles as a dispersion with enhanced kinetic stability and the applications for the conservation of sandstone monuments. agents preserve the wall porosity and therefore ensure long-lasting wall painting consolidation, permeability to moisture evaporation as in the wall before treatment and most of them do not hinder subsequent restoration. Ferroni and Dini [10, 11] elaborated a method to clean and consolidate stones, wall paintings 31Rodorico Giorgi, Luigi Dei, Piero Baglioni, A New Method for Consolidating Wall Paintings Based on Dispersions of Lime in Alcohol.

(Predavanje održano u Ludbregu 26. 5. In particular, the so-called Ferroni–Dini method, designed for the conservation of sulfate polluted wall paintings, consists in applying ammonium carbonate and barium hydroxide aqueous solution loaded on poultices, in a two-step procedure (see reaction scheme): while ammonium carbonate turns gypsum into soluble ammonium sulfate , which is.

Desulfatation and consolidation was performed with the Ferroni–Dini method." (Credit for photos: Daniela Dini; credit for caption: CSGI). And below are other photos of wall paintings by Santi di. This innovative treatment was unanimously considered as the “birth” of a new methodological and technological approach to the restoration of wall paintings. Since then, this method, known as Ferroni-Dini method or Barium treatment, became a well-established approach to address the problem of sulphation which concerns, in different forms and.

This process is called sulphatisation and the effects on the paintings are loss of colour transparency and loss of cohesion of the painted layers. The present paper reviews the sulphatisation process and the peculiarities of both the Ferroni-Dini method and Ca(OH) 2 nanotechnology for pre-consolidation, cleaning and consolidation of wall. the ratio of ethanol and n-propanol. Especially, a technique, which combined the Ferroni-Dini method and dispersion of Ca(OH)2 nanoparticles. interesting materials used to perform consolidation of stone sculptures, monuments, mortars or wall paintings [4]. Calcium hydroxide reacts with carbon dioxide in the air, producing calcium. The so-called Ferroni–Dini method (two steps: the application of a saturated solution of ammonium carbonate, (NH 4) 2 CO 3, and the treatment with a barium hydroxide solution, Ba(OH) 2), also called the 'barium' method, has long been the acknowledged method for the removal of salts that threaten paintings, reinforcing at the same time the. For these reasons, we propose a new method for the consolidation of building stone capable of cleaning the gypsum crust and consolidating stones at the same time, based in the Ferroni-Dini method [1] and using DAP.
